The Muscle: Back

1. Begin on your belly with hands underneath your shoulders, elbows touching your rib cage, and with your knees wide, feet up toward the ceiling, and toes pointed together to make a triangle. 2. In a slow, controlled motion, perform one half-cobra push-up — pushing through your palms until your chest lifts as high off the floor as you can get it without straightening your arms. 3. After holding for a moment, bring your chest down and move into a grasshopper lift by raising your knees off the mat.

The Muscle: Arms

1. Hold on to a bench or weight stand with one hand for support. 2. Bend your knees, bring your torso forward, and stick your butt out. Make sure you keep your back flat and your head up. 3. With a weight in your other hand (start light and gradually increase), bring your elbow up so your upper arm is parallel to the ground with a 90-degree angle between your forearm and upper arm; extend your arm straight back, keeping it close to the body.

Lewin: “Brides love this one because of the burn; you know it’s working. You feel like a superhero.’’

The Muscle: Butt

1. Position yourself into a low squat; squeeze the glutes. 2. Walk forward with your hands placed on your thighs for support and pop your booty two times with every step. 3. Stabilize the booty bus by also engaging your quads, hamstrings, calves, and abs.

Marshall: “Yes, this tightens your butt, but it’s also a dance move you can do at the reception.”

The Muscle: All of Them

1. Start in plank pose. 2. Jump both feet forward so they’re just behind your hands, then stand up straight. 3. Jump up, moving one leg back directly behind you and the other leg forward in front of you. 4. Sink into a lunge when you land. 5. Jump up from this position, switching the placement of your legs midair, and sink down again. 6. Jump up and bring your feet back to center. 7. Bring your hands to the floor and jump both legs back into plank.

Light: “If you hate burpees, you’re really gonna hate them when you add the switch lunge. That’s why this is the perfect move for when you’re prepping for a wedding — when you have that extra motivation.”
